Answer:
Step-by-step explanation:
Multiply both sides: by <em>x+c</em>
a(x+c)=
(x+c)
Simplify: a(x+c)=b-2x
Expand: ax+ac=b-2x
Subtract <em>ac</em> from both sides: ax+ac-ac=b-2x-ac
Simplify: ax=b-2x-ac
Add<em> 2x</em> to both sides: ax+2x=b-2x-ac+2x
Simplify: ax+2x=b-ac
Factor <em>ax+2x</em>: x(a+2)
x(a+2)=b-ac
Divide both sides by <em>a+2: </em>
=

Answer:
her total was 11.
Step-by-step explanation:
4.282 is rounded to 4.300
If angle ABC is 90°, then angle CBD is 90°:
Angle ABD=90°
3x°=90°
3x=90
Solving for x:
3x/3=90/3
x=30
Angle CBD=90°
(2x+3y)°=90°
2x+3y=90
x=30
2(30)+3y=90
60+3y=90
Solving for y:
60+3y-60=90-60
3y=30
3y/3=30/3
y=10
Answer: Option a. 10
Answer:
This would be an algebraic problem if that's what you're asking.
